After college (see my top-level reply) I became the same way for some years. I eventually came to realize that a lot of my books truly no longer held any value to me, and I would almost certainly never open them again. I've managed to clear out about 10-15% of my collection, which actually did marvels for making the place look tidier.
Of course, I'm also continuing to buy more books, so, um...
Maybe someday I'll come to like ebooks just as much, but so far I'm not counting on it.
Yeah, for a technology enthusiast, I'm something of a luddite when it comes to books. I mean, not totally, as I've purchased 3 Nooks over the years (the last one because I lost the first 2, but still...)
I've found that e-books occupy a certain niche for me, and they haven't replaced dead-tree books in general. I love my ebook reader when flying (I can carry hundreds or thousands of books on the plane with me! How awesome is that?), and when reading in bed at night (when I'm ready to go to sleep, I just close the cover and close my eyes. No need to fumble around with the lamp, etc.)
That said, most of my ebooks are pirated and are limited to specific niche topics - my collection of ebooks doesn't even begin to rival my physical library in breadth. Maybe eventually, but we'll see...
